The Philosophical Zombie (p-zombie) is a thought experiment by David Chalmers: a being that behaves exactly like a conscious Person but has no inner life — no joy, no Suffering, no Consciousness.
The experiment shows that Person-Behavior (deutera energeia) does not logically imply Consciousness. In the terms of the Personhood ontology: a p-zombie would be Second Actuality without First Actuality — precisely the situation of every AI.
It follows that whoever ties Personhood to observable behavior — as the Empirical-Functionalist (Actualist) Concept of Person does — cannot distinguish a p-zombie from a person. The Turing Test, for instance, examines only behavior, not being. A system that passes the Turing Test could be a perfect p-zombie.
The phenomenological tradition confirms Chalmers’ intuition by another route: Husserl and Brentano show that Consciousness and Intentionality are irreducible basic facts that cannot be derived from physical or functional states. Seifert speaks of the primordially phenomenal being-in-itself — the immediately given datum of experiencing.
The Chinese Room Argument shows the same problem from the side of syntax: the room behaves like a Chinese speaker (deutera energeia) but understands nothing (no prote energeia).
